Comprehensive Rotating Equipment Foundation Solutions

Comprehensive Rotating
Equipment Foundation Solutions

Rotating and reciprocating equipment foundation systems are subjected to dynamic forces – which over time can lead to degradation – which may significantly impact the performance of the machinery they are designed to support.

Investigation

STRUCTURAL TECHNOLOGIES offers highly specialized assessment and engineering services for equipment foundation systems. These services are designed to complement and enhance machinery analysis. The objective of a comprehensive condition assessment is to identify the root cause of problems and the level of damage.

Products & Design Support

Our team helps to select the best materials and technologies including items such as concrete, grout and anchor bolts to improve the performance and longevity of the foundation system. Our solutions are comprehensive and address major considerations when working with dynamic machinery and their foundations.

Turnkey Solutions

When STRUCTURAL TECHNOLOGIES teams with one of Structural Group’s specialty contracting companies – we offer our turnkey Investigate-Design-Build (IDB) approach to provide a seamless process from initial design through installation with single-source responsibility. This approach is ideally suited for industrial and power clients looking to perform repair and maintenance during scheduled turnarounds and outages.

  • Gas/Steam Turbines
  • Turbo Pumps
  • Compressors
  • Fans
  • Motors
  • Centrifuges
  • Engines

Investigation, Testing & Analysis of Foundation Systems

STRUCTURAL TECHNOLOGIES offers a range of testing and deliverables to thoroughly assess and analyze the condition of a foundation system, aimed at identifying the root cause of deterioration. An initial assessment may include review of the foundation system design, equipment data and a visual observation with the equipment running. If a full condition assessment is required, STRUCTURAL TECHNOLOGIES performs a series of advanced testing to determine the condition of the foundation system.

Foundation Vibration Analysis

Foundation Vibration Analysis
Designed to complement and enhance owners’ in-house machinery analysis, our engineers utilize the data acquired to perform free vibration, harmonic and steady state analysis to study the foundation behavior under load.

Finite Element Analysis

Finite Element Analysis
Vibration data is used in conjunction with Finite Element Analysis (FEA) to model various repair solutions to predict future performance of the foundation system – to help select the best repair solution.

Reporting on Foundation Condition Assessment

If a full condition assessment is required, STRUCTURAL TECHNOLOGIES performs a series of advanced testing to determine the condition of the foundation system. Following the field investigation, the client receives a comprehensive report that includes:

  • Investigation summary
  • Laboratory summary
  • Data analysis
  • Foundation behavior modeling (with vibration monitoring)
  • Root cause determination

By incorporating the capabilities of Structural Group’s contracting companies, our final report and client briefing can also provide repair alternatives and their associated order of magnitude repair investments.
